I am trying to display comments + comment form per node in a view of nodes following this answer. So I'm trying full content display with row style options, which works perfectly on another site I am working on, but on this one, I don't have the "Display comments" toggle box
So I have reinstall the site and disable every thing I could : contrib modules / themes and templates / custom code / libraries / fields & comment fields / all content types trying with new ones / uninstall & reinstall comment modules / combination of permissions for all/just admin in view-post-skip options. Still nothing.
Anyone has seen this before?
